The Portugal captain scored his ninth goal in just five appearances in Tuesday's win over Copenhagen - a game in which he also missed a penalty - but the 28-year-old has warned he is not yet back to his best following injury.

"The objective is complete, the team played very well on a field that was very bad. I've broken a record in the Champions League and I'm very happy," he was quoted as saying by the club's official website.

"The team is very good, confident, and playing attractive football.

"I'm coming back bit by bit. I'm at a good level, but not my best. I feel good and eager to help the team.

"All goals are important for the team and it was special to break the record today, but I don't think about records. The main goal is to win."

Defender Alvaro Arbeloa admitted Ronaldo was annoyed to have missed his spot-kick but felt his side performed well on a difficult surface in Denmark.

"This is not an easy stadium, especially if we consider how the pitch was," he told TVE.

"We look to Cristiano every day, regardless of records. He left the pitch angry because he missed the penalty and does not like to fail, but the important thing is the victory.

"The team has gone from strength to strength. He's doing better every day and the proof is the great group stage."
